6. English language and literature: More than 52 percent of English majors said they're underemployed. More than 21 percent said they're not using their education in their job. Starting median pay: $39,700. Common underemployed jobs: Admin assistant, paralegal, office manager.

2. Business management and administration: Sixty percent of majors said they're underemployed. More than 81 percent said they're underpaid. Starting median pay: $44,300. Common underemployed jobs: Office manager, customer service rep, retail store manager. (This major may be a surprise here, but it's often a step toward an MBA, and not a job right out of school).

1. Patient services representative: 87 percent of people with this job said they're underemployed, making it PayScale's worst job to find full-time work. One in four workers in this field said they aren't using their education or training on the job. And more than three-fourths said they're underpaid. Starting median pay: $29,500.

If that sounds like you, you're probably one of millions of Americans considered underemployed, in which they can't find full-time work, or can't find well-paying, full-time work in their field of study or experience.

As many as 22 million people can be counted as underemployed, despite more people than ever having college degrees, found PayScale's new study on the phenomenon. At the same time, many employers say they can't find qualified workers for job openings. (That's the so-called "skills gap").

Patterns? Women dominate jobs plagued with underemployment, PayScale found. People in STEM fields generally do not struggle to find full-time, well-paying jobs. Underemployment affects both college-educated and uneducated workers. And millenials struggle the most in finding full-time, well-paying, education-relevant work.

So which jobs and college majors have the most underemployment? And how does the much maligned English major fare on the ranking? Click the slideshow for a look at PayScale's study.

Methodology: PayScale said more than 40 percent of people surveyed said they felt underemployed. (The career site didn't say how many people it surveyed, but the Washington Post said it was 68,000).

PayScale also defined underemployment more broadly than the stricter federal definition of simply having to settle for part-time work, when you want full-time work. PayScale included the criteria of "feeling underpaid," or feeling like your pay doesn't match your level of education or training.
